MIL-M-38510-13 Microcircuits, Digital, Bipolar, Ttl, Counters Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, TTL, binary and decade counters. Two product assurance classes and a choice of case outlines and lead finishes are provided for each type and are reflected in the complete part number. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.
